The Effect of Climate Variability on Main Components of Cow Milk in Iran
(2016-11-21)
The main purpose of this study is to assess the relationship between six bioclimatic indices
for cattle (temperature humidity (THI), environmental stress (ESI), equivalent temperature
(ESI), heat load (HLI), modified heat load (HLInew) and respiratory rate predictor(RRP)) and
fundamental milk components (fat, protein, and milk yield) considering uncertainty. The climate
parameters used to calculate the climate indices were taken from the NASA-Modern Era

Urban agriculture: How bottom-up initiatives are impacting space and policies in São Paulo
(Department of Organic Food Quality and Food Culture at the University of Kassel, Germany and Federation of German Scientists (VDW), 2017-12-29)
The growing demand for the creation of urban gardens in large cities has created a discussion about the need for green spaces in cities that fulfil multiple functions. Beyond the production of fresh and healthy food, these spaces should also connect citizens, transform the public space through collective action, and engage the participation of society in the policies and planning for a greener city with a better quality of life. This paper addresses the case of São Paulo specifically and illustrates how urban gardens ...

The case for citizen science in urban agriculture research
(Department of Organic Food Quality and Food Culture at the University of Kassel, Germany and Federation of German Scientists (VDW), 2017-12-29)
In an uncertain future of climate change and constrained resources, urban agriculture is widely viewed as a sustainable and scalable approach to improving food security. While its social, health and wellbeing benefits are well documented, there is a major knowledge gap in terms of the financial accessibility of urban food production for all households. The implications are far-reaching: if urban agriculture is purely a middle-class discretionary activity, then it will play a limited role in improving food security ...

Dueling the consumer-activist dualism: The consumption experiences of modern food activists
(Department of Organic Food Quality and Food Culture at the University of Kassel, Germany and Federation of German Scientists (VDW), 2017-12-29)
Consumer-based food activism (CBFA) is increasingly a symbol of modern politics. Through eating, food purchasing, and other consumer behaviours, individuals advocate for social justice causes. However, CBFA is critiqued for being enabled or produced by neoliberal ideologies, which emphasize individuals’ market-based positions as consumers over other (activist) roles, effectively diminishing any influence such personal behaviours have on changing broader structural systems. This project is an exploratory study ...

Alternative plant protein sources for pigs and chickens in the tropics – nutritional value and constraints: a review
(Kassel University Press, 2012)
In the tropics, a large number of smallholder farms contribute significantly to food security by raising pigs and poultry for domestic consumption and for sale on local markets. The high cost and, sometimes, the lack of availability of commercial protein supplements is one of the main limitations to efficient animal production by smallholders. Locally-grown forages and grain legumes offer ecological benefits such as nitrogen fixation, soil improvement, and erosion control which contribute to improve cropping efficiency. ...

Is export orientation a major motivator for the adoption of food safety systems in the Turkish dried fig firms?
(Kassel University Press, 2012)
Food safety management systems (FSMSs) and the scrutinisation of the food safety practices that are intended for adoption on the firm level both offer strategic value to the dried fig sector. This study aims to prove the hypothesis that export orientation is a major motivating force for the adoption of food safety systems in the Turkish dried fig firms. Data were obtained from 91 dried fig firms located in Aydin, Turkey. Interviews were carried out with firms’ managers/owners using a face-to-face questionnaire designed ...

Effects of dietary lipid source on growth, digestibility and tissue fatty acid composition of Heterobranchus longifilis fingerlings
(Kassel University Press, 2012)
One of the major problems facing aquaculture is the inadequate supply of fish oil mostly used for fish feed manufacturing. The continued growth in aquaculture production cannot depend on this finite feed resources, therefore, it is imperative that cheap and readily available substitutes that do not compromise fish growth and fillet quality be found. To achieve this, a 12-week feeding trial with Heterobranchus longifilis fed diets differing in lipid source was conducted. Diets were supplemented with 6% lipid as fish ...

Strategies for coping with feed scarcity among urban and peri-urban livestock farmers in Kampala, Uganda
(Kassel University Press, 2012)
Livestock keeping is increasingly becoming more popular in Kampala, the capital city of Uganda. However, lack of feed is a real challenge. Inadequate feed supply in urban areas is due to many interacting factors, which include among others land shortage, high cost of feeds, climate risks and poor quality of feeds. The objective of this study was to identify and examine the effectiveness of the strategies adopted by livestock farmers in urban and peri-urban areas of Kampala, Uganda to cope with feed scarcity. A total ...

Effects of red brick production on land use, household income, and greenhouse gas emissions in Khartoum, Sudan
(Kassel University Press, 2012)
In Khartoum (Sudan) a particular factor shaping urban land use is the rapid expansion of red brick making (BM) for the construction of houses which occurs on the most fertile agricultural Gerif soils along the Nile banks. The objectives of this study were to assess the profitability of BM, to explore the income distribution among farmers and kiln owners, to measure the dry matter (DM), nitrogen (N), phosphorus (P), potassium (K) and organic carbon (C_org) in cow dung used for BM, and to estimate the greenhouse gas ...

Influence of education levels on dissemination of soil fertility management information in the central highlands of Kenya
(Kassel University Press, 2012)
Inadequate links between researchers and farmers has resulted in low uptake of research advances recommended to improve food security in the central highlands of Kenya. Access to timely and accurate information by extension agents and farmers is paramount in dissemination of soil fertility management practices. Hence, the study sought to investigate the effect of education levels on communication channels used to disseminate soil fertility technologies in the Central highlands of Kenya. Questionnaires were used to ...
